Description The term spot repair refers to all repairs in which the repaired area has color blended invisibly into the existing finish. As a result, the car refinisher is not compelled to spray large panels in the case of minor damage. The spot repair technique also enables minor differences in color and effect between the original car finish and the repair to be made invisible. Safety Considerations Use suitable personal protection. AkzoNobel recommends the use of a fresh air supply respirator. Refer to the product Safety Data Sheet (SDS) for more complete safety information.

3 Stage Repair Let-Down Panels Let down panels are used as an aid in estimating the number of second layer or mid-coat applications are needed to achieve a color match for three stage colors. When used as a tool for comparing the variety of applications to the repair vehicle the painter can determine the appropriate number of mid-coat applications to arrive at a suitable color match for the job. The color of the foundation coat and the thickness of the mid-coat determine the hue of three stage colors. Therefore the foundation color must be matched before assessing the mid-coat. Some vehicles may have an area on the vehicle that has not had the second layer color applied. This area can be used to confirm the accuracy of the first layer color. Typical placements of this un-coated area include; rocker panel sills, under hoods or inside trunks. When completed, your let down panel should also include an area that has not been painted with the second layer color. You can then use the let-down panel to assess both the first layer color and the mid-coat color & application prior to painting the vehicle. When clear coating the panel if only one half of the panel is cleared it will allow the painter to assess the match of the repair during repair application. Note: When spraying an actual repair stop one coat short of the estimated number of coats of the mid-coat. Using the un-cleared side of the letdown do an evaluation of your progress and determine how many more coats of the second layer may be needed. Let-Down Panel Application 1) Apply the foundation color to a spray-out panel and dry. 2) Mask off approximately 6 equal segments on the spray-out. 3) Apply mid-coat to the first un-masked area. It is important to apply the mid-coat exactly as you would if you were spraying a repair. Flash dry. 4) Remove masking from the next application area and apply mid-coat to the 1st application area and the 2nd. 5) Repeat until each area except one has been coated with mid-coat color. Flash for 20 minutes. 6) Mask off 1/2 of the panel across the panel vertically. 7) Clear coat the un-masked portion of the let-down panel. 6 / 11

De-Gloss areas C and D with a D.A. using #P1000 dry and a 3M Interface pad or 3M Gray Scotch-Brite and PlastoBlend and water. Application Metallic Foundation Spray medium coats in areas A and B until covered. Extend each coat slightly making the final coat fade into the original finish. Application Metallic Blending Foundation Mixing Mix 100 parts of ready to spray metallic foundation color with 50 parts of ready to spray mid-coat color. Note: Transparency enhancer may be added if needed to make the foundation easier to blend. Application Metallic Blending Foundation Spray 1-2 single coats fading out into area C. Note: Layer 1 must blend invisibly into the original finish. When the 1st layer in a 3-Step color is applied varying amounts of the original effect show through the application. For this reason a corresponding amount of 2nd layer color most be applied to create a seamless repair. Therefore a staggered application is used. Application Mid Coat 1st coat, spray a wet coat in area A. 2nd coat, spray a wet coat to the end of the layer one blending foundation. 3rd coat, spray a wet coat between areas B/C. 4th coat, blend into area D. 7 / 11

Note: Foundation must blend invisibly into the original finish. When the 1st layer foundation in a 3-Step color is applied varying amounts of the original effect show through the application. For this reason a corresponding amount of pearl mid-coat color must be applied to create a seamless repair. Therefore a staggered application is used. The method below will also allow the painter to better judge where more pearl mid-coat is needed on the repair. Application Mid Coat 1st coat, spray a wet coat in area A. 2nd coat, spray a wet coat to the end of the layer one blending foundation. 3rd coat, spray a wet coat between areas B/C. 4th coat, blend into area D. 8 / 11
Film Thickness Using Suitable Application Drying / Curing Autowave solid, metallic and pearl colors: 0.4-0.9 mils The total dry layer thickness of Autowave should not exceed 1.2 mils Drying times are stated a recommended application method, film thickness and object temperature. Recoat Time Humidity and airflow will influence the Autowave flash off and drying times. These times can be reduced to a minimum by using air accelerator systems with a distance of 3 feet from the object, thus increasing the airflow over the object. When heat is used for drying, allow object to cool down to application temperature before proceeding with color or clearcoat application Prior to clearcoat application: o Minimum 15 minutes at 75 F (24 C). Thorough drying after basecoat application is necessary o Maximum 24 hours at 75 F (24 C). Should this maximum time be exceeded, abrade the surface and apply another coat.

Sanding / De-Nibbing Masking Cleaning of Equipment Theoretical Coverage Allow Autowave to dry sufficiently, at least 20 minutes at 75 F (24 C). Then lightly dry sand the damaged area with #P600 to #P1000 dry sanding paper. Thoroughly remove sanding dust residue before continuing Autowave application. Autowave colors can be taped (i.e. two toning) after 20 minutes flash-off at 75 F (24 C). o Increasing air movement especially with increased temperature improves the ability to apply masking on Autowave. o Let the object cool down to ambient temperature before masking. Clean and rinse the spray gun thoroughly after use with Autowave Gun Cleaner. Final rinse the spray gun with Activator WB prior to Autowave use. o Do not use any conventional thinner unless removing dried Autowave deposits. o Do not soak the spray gun for long periods either with Autowave Gun cleaner or Activator WB. Theoretical coverage is dependent of many factors. These may include; the shape of the object, surface smoothness, application technique and other application variables among others. 160 m2. / liter ready to spray VOC / Regulatory Information The VOC content of this product in ready to use form is <3.5 lb. /gallon.
